Predictors of Adherence to Treatment in Women With Fibromyalgia

Factors that influence medication adherence in women with fibromyalgia: A path analysis

AIMS

To investigate the relationships between depression symptoms, perceived stigma, disease severity, patient-provider communication and medication adherence in fibromyalgia patients. The objectives were to explore how these factors influence treatment adherence and to develop a comprehensive model illustrating their interconnections.

BACKGROUND

Fibromyalgia is a chronic pain syndrome with fatigue, sleep issues and idiopathic pain. Medication adherence is limited by insufficient symptom relief, side effects and costs. Stigma further complicates fibromyalgia. Disease severity affects patient-provider communication. Associations between depression, stigma, severity, communication and adherence in fibromyalgia are unclear.

DESIGN

A cross-sectional, correlational study.

METHODS

The STROBE guidelines for cross-sectional studies were followed. Participants included Hebrew-speaking participants who were members of two Facebook groups: 'Shades of Purple' and 'Fibromyalgia- Get to Know!' Between February and April 2022. They undertook evaluations using The Patient Health Questionnaire-9 to gauge depression symptoms, assessed perceived stigma, utilised The Revised Fibromyalgia Impact Questionnaire to determine disease severity, employed The Patient Reaction Assessment questionnaire for patient-provider communication, and used the 8-item Morisky Medication Adherence Scale (MMAS-8). Associations between the variables were explored using Pearson's correlations and path analyses.

RESULTS

The study included 141 women with fibromyalgia, aged 22 to 76 years. Most reported having a stable partner (69.5%) and 75.2% had children. The treatment adherence levels were as follows: 53.2% (N = 75)-low, 33.3% (N = 47)-medium and 13.5% (N = 19)-high. Depression positively correlated with stigma. Stigma negatively correlated with patient-provider communication. Patient-provider communication positively correlated with treatment adherence. A significant negative indirect effect of depression on treatment adherence through stigma and patient-provider communication was found.

CONCLUSIONS

Perceived stigma and patient-provider communication played a mediating role in the relationships between depression and treatment adherence among women with fibromyalgia.

RELEVANCE TO CLINICAL PRACTICE

Addressing stigma related to fibromyalgia and effective patient-provider communication can positively influence treatment adherence.

Epistemic Injustice and Nonmaleficence

Epistemic injustice has undergone a steady growth in the medical ethics literature throughout the last decade as many ethicists have found it to be a powerful tool for describing and assessing morally problematic situations in healthcare. However, surprisingly scarce attention has been devoted to how epistemic injustice relates to physicians' professional duties on a conceptual level. I argue that epistemic injustice, specifically testimonial, collides with physicians' duty of nonmaleficence and should thus be actively fought against in healthcare encounters on the ground of professional conduct. I do so by fleshing out how Fricker's conception of testimonial injustice conflicts with the duty of nonmaleficence as defined in Beauchamp and Childress on theoretical grounds. From there, I argue that testimonial injustice produces two distinct types of harm, epistemic and non-epistemic. Epistemic harms are harms inflicted by the physician to the patient qua knower, whereas non-epistemic harms are inflicted to the patient qua patient. This latter case holds serious clinical implications and represent a failure of the process of due care on the part of the physician. I illustrate this through examples taken from the literature on fibromyalgia syndrome and show how testimonial injustice causes wrongful harm to patients, making it maleficent practice. Finally, I conclude on why nonmaleficence as a principle will not be normatively enough to fully address the problem of epistemic injustice in healthcare but nevertheless may serve as a good starting point in attempting to do so.

Altered motivation states for physical activity and 'appetite' for movement as compensatory mechanisms limiting the efficacy of exercise training for weight loss

Weight loss is a major motive for engaging in exercise, despite substantial evidence that exercise training results in compensatory responses that inhibit significant weight loss. According to the Laws of Thermodynamics and the CICO (Calories in, Calories out) model, increased exercise-induced energy expenditure (EE), in the absence of any compensatory increase in energy intake, should result in an energy deficit leading to reductions of body mass. However, the expected negative energy balance is met with both volitional and non-volitional (metabolic and behavioral) compensatory responses. A commonly reported compensatory response to exercise is increased food intake (i.e., Calories in) due to increased hunger, increased desire for certain foods, and/or changes in health beliefs. On the other side of the CICO model, exercise training can instigate compensatory reductions in EE that resist the maintenance of an energy deficit. This may be due to decreases in non-exercise activity thermogenesis (NEAT), increases in sedentary behavior, or alterations in sleep. Related to this EE compensation, the motivational states associated with the desire to be active tend to be overlooked when considering compensatory changes in non-exercise activity. For example, exercise-induced alterations in the wanting of physical activity could be a mechanism promoting compensatory reductions in EE. Thus, one's desires, urges or cravings for movement-also known as "motivation states" or "appetence for activity"-are thought to be proximal instigators of movement. Motivation states for activity may be influenced by genetic, metabolic, and psychological drives for activity (and inactivity), and such states are susceptible to fatigue-or reward-induced responses, which may account for reductions in NEAT in response to exercise training. Further, although the current data are limited, recent investigations have demonstrated that motivation states for physical activity are dampened by exercise and increase after periods of sedentarism. Collectively, this evidence points to additional compensatory mechanisms, associated with motivational states, by which impositions in exercise-induced changes in energy balance may be met with resistance, thus resulting in attenuated weight loss.

Comparative efficacy and acceptability of non-pharmacological interventions in fibromyalgia: Protocol for a network meta-analysis

INTRODUCTION

Although several non-pharmacological interventions have been tested in the management of Fibromyalgia (FM), there is little consensus regarding the best options for the treatment of this health condition. The purpose of this network meta-analysis (NMA) is to investigate the comparative efficacy and acceptability of non-pharmacological interventions for FM, in order to assist clinical decision making through a ranking of interventions in relation to the most important clinical outcomes in these patients.

METHODS AND ANALYSIS

We will perform a systematic search to identify randomised controlled trials of non-pharmacological interventions endorsed in guidelines and systematic reviews. Information sources searched will include major bibliographic databases without language or date restrictions (MEDLINE, Cochrane Library, EMBASE, AMED, PsycINFO and PEDro). Our primary outcomes will be pain intensity, patient-reported quality of life (QoL), and acceptability of treatment will be our secondary outcome. Risk of bias of the included trials will be assessed using the Cochrane risk of bias tool (RoB2). For each pairwise comparison between the different interventions, we will present mean differences (MDs) for pain intensity and QoL outcomes and Relative Risks (RRs) for acceptability, both with respective 95% confidence intervals (CIs). Initially, standard pairwise meta-analyses will be performed using a DerSimonian-Laird random effects model for all comparisons with at least two trials and then we will perform a frequentist NMA using the methodology of multivariate meta-analysis assuming a common heterogeneity parameter, using the mvmeta command and network suite in STATA. In the NMA, two different types of control group, such as placebo/sham and no intervention/waiting list will be combined as one node called "Control". The competing interventions will be ranked using the P-score, which is the frequentist analogue of surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at immediate- (intervention duration of up to 2 weeks), short- (over 2 weeks up to 12 weeks) and long-terms (over 12 weeks). The confidence in the results from NMA will be assessed using the Confidence in Network Meta-analysis (CINeMA) framework.

ETHICS AND DISSEMINATION

This work synthesises evidence from previously published studies and does not require ethics review or approval. A manuscript describing the findings will be submitted for publication in a peer-reviewed scientific journal.

A Novel Method for Digital Pain Assessment Using Abstract Animations: Human-Centered Design Approach

Background

Patients with chronic pain face several challenges in using clinical tools to help them monitor, understand, and make meaningful decisions about their pain conditions. Our group previously presented data on Painimation, a novel electronic tool for communicating and assessing pain.

Objective

This paper describes the human-centered design and development approach (inspiration, ideation, and implementation) that led to the creation of Painimation.

Methods

We planned an iterative and cyclical development process that included stakeholder engagement and feedback from users. Stakeholders included patients with acute and chronic pain, health care providers, and design students. Target users were adults with acute or chronic pain who needed clinical assessment and tracking of the course of their pain over time. Phase I (inspiration) consisted of empathizing with users, understanding how patients experience pain, and identifying the barriers to accurately expressing and assessing pain. This phase involved understanding how patients communicate pain symptoms to providers, as well as defining limitations of current models of clinical pain assessment tools. In Phase II (ideate) we conceptualized and evaluated different approaches to expressing and assessing pain. The most promising concept was developed through an iterative process that involved end users and stakeholders. In Phase III (implementation), based on stakeholder feedback from initial designs and prototypes of abstract pain animations (painimations), we incorporated all concepts to test a minimally viable product, a fully functioning pain assessment app. We then gathered feedback through an agile development process and applied this feedback to finalizing a testable version of the app that could ultimately be used in a pain clinic.

Results

Engaging intended users and stakeholders in an iterative, human-centered design process identified 5 criteria that a pain assessment tool would need to meet to be effective in the medical setting. These criteria were used as guiding design principles to generate a series of pain assessment concept ideas. This human-centered approach generated 8 highly visual painimations that were found to be acceptable and useable for communicating pain with medical providers, by both patients with general pain and patients with sickle cell disease (SCD). While these initial steps continued refinement of the tool, further data are needed. Agile development will allow us to continue to incorporate precision medicine tools that are validated in the clinical research arena.

Conclusions

A multiphase, human-centered design approach successfully resulted in the development of an innovation that has potential to improve the quality of medical care, particularly for underserved populations. The use of Painimation may especially benefit the medical care of minority populations with chronic and difficult-to-treat pain, such as adults with SCD. The insights generated from this study can be applied to the development of patient-reported outcomes tools that are more patient-centered, engaging, and effective.

Effectiveness of High-Frequency Transcranial Magnetic Stimulation and Physical Exercise in Women With Fibromyalgia: A Randomized Controlled Trial

OBJECTIVE

Fibromyalgia (FM) is characterized by chronic widespread pain and both physical and emotional alterations, which in turn may affect the individual's quality of life. Thus, interventions aimed at treating such symptoms, without increasing fatigue, are needed. The aim of this study was to explore the effect of high-frequency transcranial magnetic stimulation (HF-TMS) and physical exercise (PE) on pain, impact of FM, physical conditioning, and emotional status in women with FM.

METHODS

Forty-nine women with FM were randomly allocated to: (1) a PE group (PEG, n = 16), who underwent an 8-week (two 60-minute sessions/wk) low-intensity PE program; (2) a TMS group (TMSG, n = 17) receiving a 2-week (five 20-minute sessions/wk) HF-TMS intervention; and (3) a control group (CG, n = 16). Pain (ie, perceived pain and average pressure pain threshold), perceived impact of FM (ie, overall impact, symptoms, and perceived physical function), physical conditioning (ie, endurance and functional capacity, fatigue, gait velocity, and power), and emotional status (ie, anxiety, depression, stress, and satisfaction) were assessed at baseline (T0) and after the intervention (T1, at 2 weeks for TMSG and at 8 weeks for PEG and CG).

RESULTS

The TMSG showed significant improvement in all studied variables after the intervention except for satisfaction, whereas the PEG showed improved average pressure pain threshold, perceived overall impact of FM and total score, endurance and functional capacity, velocity and power, anxiety, depression, and stress. In contrast, the CG showed no improvements in any variable.

CONCLUSION

Both PE and HF-TMS are effective in improving pain, impact of FM, physical conditioning, and emotional status in people with FM; HF-TMS achieved larger improvements in emotional status than PE.

IMPACT

TMS and PE have similar benefits for physical status, whereas TMS has greater benefits than PE for emotional status in women with FM.

Effective recruitment strategies in an exercise trial for patients with fibromyalgia

BACKGROUND

Recruitment of fibromyalgia populations into long-term clinical trials involving exercise interventions is a challenge. We evaluated the cost and randomization yields of various recruitment methods used for a fibromyalgia trial in an urban setting. We also investigated differences in participant characteristics and exercise intervention adherence based on recruitment source.

METHODS

We recruited individuals with fibromyalgia in the greater Boston area to a randomized controlled trial (RCT) using six recruitment strategies: newspaper advertisements, web advertisements, flyers, clinic referrals, direct mailing to patients in a clinic database, and word of mouth. We used the American College of Rheumatology 1990 and 2010 diagnostic criteria to screen and enroll participants. During an initial phone call to an interested participant, the study staff asked how they heard about the study. In this study, we compared the cost and yield of the six recruitment strategies as well as baseline characteristics, adherence, and attendance rates of participants across strategies.

RESULTS

Our recruitment resulted in 651 prescreens, 272 screening visits, and 226 randomized participants. Advertisements in a local commuter newspaper were most effective, providing 113 of 226 randomizations, albeit high cost ($212 per randomized participant). Low-cost recruitment strategies included clinical referrals and web advertisements, but they only provided 32 and 16 randomizations. Community-based strategies including advertisement and flyers recruited a more racially diverse participant sample than clinic referrals and mailing or calling patients. There was no evidence of difference in adherence among participants recruited from various strategies.

CONCLUSIONS

Newspaper advertisement was the most effective and most expensive method per randomized participant for recruiting large numbers of individuals with fibromyalgia in an urban setting. Community-based strategies recruited a more racially diverse cohort than clinic-based strategies.

Fibromyalgia syndrome - a risk factor for poor outcomes following orthopaedic surgery: A systematic review

BACKGROUND

Fibromyalgia (FM) is a complex syndrome incorporating many features associated with poor outcome in orthopaedic surgery. Aim of the present review was to comprehensively characterize the available evidence on the consequences of pre-existent FM on the outcomes of orthopaedic surgery.

METHODS

We performed a systematic search in MedLine and Web of Science (WOS) to identify studies evaluating the effect of FM on patient-centred outcomes, opioids consumption and postoperative complications.

RESULTS

The search strategy identified 519 records in PubMed and 507 in WOS. A total of 27 articles were deemed eligible for inclusion in qualitative synthesis. Based on quality assessment, 10 studies were rated as good quality, 10 as fair quality and 7 as poor quality. Studies reporting the prevalence of FM in consecutive patients undergoing orthopaedic surgery (n = 19) were included in quantitative synthesis. The pooled prevalence of FM in patients undergoing orthopaedic surgery was 4.1% (95% CI: 2.4-6.8) in those receiving hip or knee surgery, 10.1% (95% CI: 5.7-17.2) in those receiving shoulder or elbow surgery and 21.0% (95% CI: 18.5-23.7) in those receiving spinal surgery. The results of our systematic review consistently report FM as a significant risk factor for less satisfaction, higher pain, worse functional outcome, increased risk for postoperative opioids prescription and higher rate of medical and surgical complications following orthopaedic surgery.

CONCLUSION

Identifying pre-existing FM in patients scheduled for elective orthopaedic surgery may help to better assess the benefit/risk ratio, improve patients' awareness and minimize any discrepancy between expectancy and results.

The Relationship between Cognitive and Emotional Factors and Healthcare and Medication Use in People Experiencing Pain: A Systematic Review

Pain conditions are among the leading causes of global disability, impacting on global healthcare utilization (HCU). Health seeking behavior might be influenced by cognitive and emotional factors (CEF), which can be tackled by specific therapies. The purpose of this study was to systematically review the evidence concerning associations between CEF and HCU in people experiencing pain. Three databases were consulted: PubMed, Web of Science and EconLit. Risk of bias was assessed using the Downs and Black Checklist (modified). A total of 90 publications (total sample n = 59,719) was included after double-blind screening. In people experiencing pain, positive associations between general anxiety symptoms, depressive symptoms and catastrophizing and pain medication use were found. Additionally, there appears to be a relationship between general anxiety and depressive symptoms and opioid use. Symptom-related anxiety and psychological distress were found to be positively related with consulting behavior. Last, a positive association between use of complementary and alternative medicine and level of perceived symptom control was confirmed in people with pain. For other relationships no evidence or inconsistent findings were found, or they were insufficiently studied to draw firm conclusions, indicating that more research on this topic is needed.

Risk for Medication Nonadherence Among Medicaid Enrollees With Fibromyalgia: Development of a Validated Risk Prediction Tool

OBJECTIVE

To develop and validate a risk assessment tool called the Prescription Medication Non-Adherence Prediction Tool (Rx-NAPT) to predict medication nonadherence in patients with fibromyalgia.

METHODS

This was a retrospective cohort study using claims data from South Carolina Medicaid. Patients with fibromyalgia who were ≥18 years old and who had filled at least 1 prescription medication for pregabalin, duloxetine, or milnacipran from January 1, 2005, through June 30, 2011 were included. Medication possession ratios (MPRs) were calculated to classify patients as adherent (MPR ≥ 80%) or nonadherent (MPR < 80%). Multivariable logistic models using 100 bootstrap replications (with replacement) were used to identify factors associated with medication nonadherence, including age, gender, race, days' supply, medication type, and fibromyalgia-related comorbidity score. Weighted β coefficients of the predictors were used to create the Rx-NAPT. Youden's J statistic was used to classify nonadherent patients into different levels of risk.

RESULTS

The study sample comprised 6,626 patients with fibromyalgia, where 4,804 (72.50%) were non-adherent and 1,822 (27.50%) were adherent to their prescribed medication(s). Logistic regression models showed that 7 predictors (gender, age, race, fibromyalgia-related comorbidity score, medication type, health maintenance organization coverage, emergency room visit) were statistically significant in ≥50% of the bootstrapped samples. The final model demonstrated reasonable discrimination (area under the curve [AUC] = 0.6224) and calibration (Hosmer-Lemeshow goodness-of-fit; P > 0.05) statistics and was validated internally (AUC = 0.6372).

CONCLUSION

Poor adherence with medication remains an important barrier to providing optimal care. Our risk prediction model provides an easy tool to help clinicians better identify patients with fibromyalgia who may not take their medications as prescribed.

What causes fibromyalgia? An online survey of patient perspectives

Fibromyalgia is a severe chronic pain condition that affects every aspect of life. Causes of the condition remain unclear, and quantitative research cannot account for patients' personal illness narratives and perceptions. This online survey gathered qualitative accounts of the perceived causes of their condition from 596 people with fibromyalgia, which were analyzed thematically. Themes were "Bodily assault, ill-health, and change"; "Emotional trauma and distress"; "Stress and vulnerability"; and "Explaining and authenticating fibromyalgia." Discussion focuses on the complexity of causation, the importance of understanding and having symptoms validated, and the potential for benefiting from patient expertise in building better practitioner-client relationships.

Pain, sleep and emotional well-being explain the lack of agreement between physician- and patient-perceived remission in early rheumatoid arthritis

BACKGROUND

Clinical response and remission are defined in multiple ways and measured with different instruments, resulting in substantial variation of the proportion of patients classified as being in remission. Therefore, the agreement between patient-perceived, physician-perceived remission and clinical response and remission definitions was determined in early rheumatoid arthritis (RA) patients. And secondly, differences in clinical and patient-reported outcomes, in patients in physician-perceived remission, between patients in and not in self-perceived remission were assessed.

METHODS

In 84 early RA patients, who received methotrexate and glucocorticoids, DAS44, ACR/EULAR Boolean-based remission, EULAR good and ACR70 response were determined after 12 weeks. Agreement between patient-perceived (phrased: "Would you say that, at this moment, your disease activity is as good as gone?"), physician-perceived remission (based on a visual analogue scale for global disease severity) and clinical response and remission definitions were calculated with the percentage of agreement and with kappa values (which corrects for change). In patients in physician-perceived remission, improvement in clinical and patient-reported outcomes (RAID) were compared between patients in and not in self-perceived remission.

RESULTS

Agreement between the assessed outcome measures differed enormously. The agreement between physician-perceived and patient-perceived remission was 64% (kappa 0.25, p < 0.01). Physician-perceived remission had the best agreement with EULAR good response (79%), and patient-perceived remission with EULAR good and ACR70 response (both 69%). Patients not in self-perceived remission improved less on RAID components, especially on pain, sleep and emotional well-being.

CONCLUSION

One-third of the early RA patients disagreed with the physician on being in remission. Those patients had less improvement on RAID components, especially on pain, sleep and emotional well-being. Together with the variability in clinical response and remission definitions, these results highlight the need to increase patient involvement in their own health care decisions.

Can images of pain enhance patient-clinician rapport in pain consultations?

A variety of treatment outcomes in chronic pain are influenced by patient-clinician rapport. Patients often report finding it difficult to explain their pain, and this potential obstacle to mutual understanding may impede patient-clinician rapport. Previous research has argued that the communication of both patients and clinicians is facilitated by the use of pain-related images in pain assessments. This study investigated whether introducing pain-related images into pain assessments would strengthen various components of patient-clinician rapport, including relative levels of affiliation and dominance, and interpersonal coordination between patient and clinician behaviour. Videos of 35 pain assessments in which pain images were present or absent were used to code behavioural displays of patient and clinician rapport at fixed intervals across the course of the assessment. Mixed modelling was used to examine patterns of patient and clinician affiliation and dominance with consultation type (Image vs Control) as a moderator. When pain images were present, clinicians showed more affiliation behaviour over the course of the consultation and there was greater correspondence between the affiliation behaviour of patient and clinician. However, relative levels of patient and clinician dominance were unaffected by the presence of pain images in consultations. Additional analyses revealed that clinicians responded directly to patients' use of pain images with displays of affiliation. Based on the results of this study, we recommend further investigation into the utility and feasibility of incorporating pain images into pain assessments to enhance patient-clinician communication.

Living Well With a Long-Term Condition: Service Users' Perspectives of a Self-Management Intervention

The outcomes of self-management interventions are commonly assessed using quantitative measurement tools, and few studies ask people with long-term conditions to explain, in their own words, what aspects of the intervention they valued. In this Grounded Theory study, a Health Trainers service in the north of England was evaluated based on interviews with eight service-users. Open, focused, and theoretical coding led to the development of a preliminary model explaining participants' experiences and perceived impact of the service. The model reflects the findings that living well with a long-term condition encompassed social connectedness, changed identities, acceptance, and self-care. Health trainers performed four related roles that were perceived to contribute to these outcomes: conceptualizer, connector, coach, and champion. The evaluation contributes a grounded theoretical understanding of a personalized self-management intervention that emphasizes the benefits of a holistic approach to enable cognitive, behavioral, emotional, and social adjustments.

Explaining unexplained pain to fibromyalgia patients: finding a narrative that is acceptable to patients and provides a rationale for evidence based interventions

As the cause of fibromyalgia is controversial, communicating with patients can be challenging, particularly if the patient adopts the narrative 'I am damaged and so I need a more powerful pain killer'. Research shows that providing patients with alternative narratives can be helpful, but it remains unclear what particular narratives are most acceptable to patients and at the same time provide a rationale for evidence based psychological and exercise interventions. This article described the development of a new narrative and the written comments made about the narrative by fibromyalgia patients. The narrative derives from a complexity theory model and provides an alternative to biogenic and psychogenic models. The model was presented to 15 patients whose comments about comprehensibility led to the final format of the narrative. In the final form, the body is presented as 'a very, very clever computer' where fibromyalgia is caused by a software rather than a hardware problem. The software problem is caused by the body adapting when people have to 'keep going' despite 'stop signals', such as pain and fatigue. The narrative provides a rationale for engaging in psychological and exercise interventions as a way of correcting the body's software. This way of explaining fibromyalgia was evaluated by a further 25 patients attending a 7-week 'body reprogramming' intervention, where the therapy was presented as correcting the body's software, and included both exercise and psychological components. Attendance at the course was 85%. Thematic analysis of written patient feedback collected after each session showed that patients found the model believable and informative, it provided hope and was empowering. Patients also indicated that they had started to implement lifestyle change with perceived benefit. Fibromyalgia patients appear to respond positively to a technology-derived narrative based on the analogy of the body as a computer.

Prevalence and determinants of medication non-adherence in chronic pain patients: a systematic review

BACKGROUND

Chronic pain is commonly treated with analgesic medication. Non-adherence to prescribed pain medication is very common and may result in sub-optimal treatment outcome. The aim of this review was to investigate the prevalence of medication non-adherence and to present determinants that may help identify patients at risk for non-adherence to analgesic medication.

METHODS

A search was performed in PubMed and Embase with systematic approach including PRISMA recommendations. Individual risk of bias was assessed and systematic data extraction was performed.

RESULTS

Twenty-five studies were included. Non-adherence rates to pain prescriptions ranged from 8% to 62% with a weighted mean of 40%. Underuse of pain medication was more common than overuse in most studies. Factors that were commonly positively associated with non-adherence were dosing frequency, polymedication, pain intensity, and concerns about pain medication. Factors negatively associated with non-adherence were age, again pain intensity and quality of the patient-caregiver relationship. Underuse was positively associated with active coping strategies and self-medication, and negatively associated with perceived need for analgesic medication. Overuse was positively associated with perceived need, pain intensity, opioid use, number of prescribed analgesics, a history of drug abuse, and smoking.

CONCLUSION

Non-adherence to analgesic medication use is very common in the chronic pain population. The choice for pharmacological therapy should not only be based upon pain diagnosis but should also take the risks of non-adherence into account. The value of adherence monitoring or adherence enhancing interventions has to be investigated in future studies.

To walk or not to walk: insights from a qualitative description study with women suffering from fibromyalgia

Walking improves health outcomes in fibromyalgia; however, there is low adherence to this practice. The aim of this research was to explore the beliefs of women suffering from fibromyalgia toward walking, and the meaning that they attribute to the behavior of walking as part of their fibromyalgia treatment. This study is a qualitative description research. Forty-six (46) women suffering from fibromyalgia and associated with local fibromyalgia associations located in four different Spanish cities (Elche, Alicante, Madrid, and Talavera de la Reina) participated in focus group discussions in the summer 2012. Thematic content analysis was performed in transcribed verbatim from interviews. Participants perceived several inhibitors for walking even when they had positive beliefs toward its therapeutic value. Whereas participants believed that walking can generate improvement in their disease and their health in general, they did not feel able to actually do so given their many physical impediments. Furthermore, participants struggled with social isolation and stigma, which was lessened through the conscious support of family. Advice from family doctors was also a very important facilitator to participants. In a health care delivery context that favors person-centered care, and in order to foster adherence to walking-based fibromyalgia treatments, it is recommended that therapeutic walking programs be tailored to each woman' individual circumstances, and developed in close collaboration with them to help them increase control over their health and their condition.

Why Do Patients with Chronic Inflammatory Rheumatic Diseases Discontinue Their Biologics? An Assessment of Patients’ Adherence Using a Self-report Questionnaire

Objective.

Concerns have been raised about nonadherence behavior among patients with chronic inflammatory rheumatic diseases (CIRD) receiving biologics. This nonadherence may be caused by various factors. The main objective was to explain why patients discontinue their biologics of their own accord.

Methods.

A quantitative and descriptive study was performed using a self-report questionnaire that was sent through the Internet to members of different patient associations. Sociodemographic data, medical and therapeutic history, management of biologic administration, previous experiences, and patients’ beliefs and perceptions about treatment efficacy and side effects were studied to explain self-discontinuation (SD).

Results.

A total of 581 patients answered the questionnaire between June 16, 2012, and July 4, 2012, including patients with ankylosing spondylitis (351/581, 60.4%), rheumatoid arthritis (196/581, 33.7%), psoriatic arthritis (30/581, 5.2%), and other CIRD (4/581, 0.7%). More than 1000 different biologics were described by the 581 patients, with a median of 2 lines per patient. Eighty-six patients discontinued their biologics of their own accord (14.8%). In a multivariate analysis, factors that were significantly related to SD were low level of pain, more than 1 line of biologics tried, self-administration of biologics, negative beliefs about the treatment, and a lack of medical and social support.

Conclusion.

Five predictive factors of this SD were identified, which should be assessed in routine with patients with CIRD receiving biologic treatment: pain, treatment history, self-administration of injections, negative beliefs about treatment, and a lack of perceived medical and social support.

Discordance of Global Assessments by Patient and Physician Is Higher in Female than in Male Patients Regardless of the Physician's Sex: Data on Patients with Rheumatoid Arthritis, Axial Spondyloarthritis, and Psoriatic Arthritis from the DANBIO Registry

OBJECTIVE

To assess the frequency of discordance in patient's (PtGA) and physician's (PGA) global assessment, and to investigate whether higher discordance in female patients compared with male patients is associated with the physician's sex in patients with rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), and psoriatic arthritis (PsA).

METHODS

PtGA, PGA, and other patient-related variables were retrieved from the Danish DANBIO registry, used nationwide to monitor patients with RA, axSpA, and PsA. A questionnaire was sent to all physicians registering in DANBIO (n = 265) regarding individual physician characteristics including sex and age. Discordance was defined as PtGA > 20 mm higher (or lower) than PGA. First encounters between patients and physicians were analyzed using descriptive statistics and mixed model regression analysis.

RESULTS

Ninety physicians (34%) returned the questionnaire and were pairwise matched with 10,282 first patient encounters (8300 patients with RA, 524 axSpA, and 1458 PsA). The frequency of discordant (PtGA > PGA) encounters (not including PGA > PtGA seen in < 2%) in RA, axSpA, and PsA was 49.0%, 48.3%, and 56.5%, respectively. Discordance was more common in female patients with high scores on functional disability, pain, and fatigue across the 3 diseases, whereas it was independent of the physician's sex.

CONCLUSION

In this study on Danish patients with RA, axSpA, and PsA, the PtGA was > 20 mm higher than the PGA in about half of the encounters, and more common in female patients of both female and male physicians. This finding highlights one of the challenges in shared decision making.

The influence of diagnosis on psychotherapy missed opportunities in a veteran population

OBJECTIVE

Canceled or unattended psychotherapy sessions are a source of concern for patients, providers, and health-care systems. Veterans are particularly likely to experience mental health problems, and yet they are also especially susceptible to variables leading to premature termination of services.

METHOD

This study examined a large (n = 2285) sample of veterans receiving psychotherapy services to determine if mental health diagnosis had an impact upon missed psychotherapy opportunities.

RESULTS

There were differential cancelation rates for individuals with different classes of disorder, and the total number of appointments a person scheduled changed the nature of the effect.

CONCLUSIONS

Health-care administrators and treatment providers should consider the specific effects of individuals with differing diagnoses when planning courses of treatment and coordinating care.

The effects of stress on physical activity and exercise

BACKGROUND

Psychological stress and physical activity (PA) are believed to be reciprocally related; however, most research examining the relationship between these constructs is devoted to the study of exercise and/or PA as an instrument to mitigate distress.

OBJECTIVE

The aim of this paper was to review the literature investigating the influence of stress on indicators of PA and exercise.

METHODS

A systematic search of Web of Science, PubMed, and SPORTDiscus was employed to find all relevant studies focusing on human participants. Search terms included "stress", "exercise", and "physical activity". A rating scale (0-9) modified for this study was utilized to assess the quality of all studies with multiple time points.

RESULTS

The literature search found 168 studies that examined the influence of stress on PA. Studies varied widely in their theoretical orientation and included perceived stress, distress, life events, job strain, role strain, and work-family conflict but not lifetime cumulative adversity. To more clearly address the question, prospective studies (n = 55) were considered for further review, the majority of which indicated that psychological stress predicts less PA (behavioral inhibition) and/or exercise or more sedentary behavior (76.4 %). Both objective (i.e., life events) and subjective (i.e., distress) measures of stress related to reduced PA. Prospective studies investigating the effects of objective markers of stress nearly all agreed (six of seven studies) that stress has a negative effect on PA. This was true for research examining (a) PA at periods of objectively varying levels of stress (i.e., final examinations vs. a control time point) and (b) chronically stressed populations (e.g., caregivers, parents of children with a cancer diagnosis) that were less likely to be active than controls over time. Studies examining older adults (>50 years), cohorts with both men and women, and larger sample sizes (n > 100) were more likely to show an inverse association. 85.7 % of higher-quality prospective research (≥ 7 on a 9-point scale) showed the same trend. Interestingly, some prospective studies (18.2 %) report evidence that PA was positively impacted by stress (behavioral activation). This should not be surprising as some individuals utilize exercise to cope with stress. Several other factors may moderate stress and PA relationships, such as stages of change for exercise. Habitually active individuals exercise more in the face of stress, and those in beginning stages exercise less. Consequently, stress may have a differential impact on exercise adoption, maintenance, and relapse. Preliminary evidence suggests that combining stress management programming with exercise interventions may allay stress-related reductions in PA, though rigorous testing of these techniques has yet to be produced.

CONCLUSIONS

Overall, the majority of the literature finds that the experience of stress impairs efforts to be physically active. Future work should center on the development of a theory explaining the mechanisms underlying the multifarious influences of stress on PA behaviors.

Adherence to pharmacological treatment of chronic nonmalignant pain in individuals aged 65 and older

BACKGROUND

Medication nonadherence is a frequent problem in the treatment of chronic conditions.

OBJECTIVE

To study the adherence to pharmacological treatment of chronic nonmalignant pain, as well as factors and patient attitudes related to nonadherence in patients aged ≥65 years.

METHODS

The cross-sectional study was conducted with a self-administered questionnaire among 100 patients aged ≥65 years by five family physicians at the Health Care Centre Mostar, Bosnia and Herzegovina.

RESULTS

According to their own statements, 57% of the patients were nonadherent, while 84% exhibited some form of nonadherence on the Morisky scale. The patients reported a mean pain intensity of 6.6 ± 2.2 on a visual analog scale. The most common deviation from the prescribed therapy was self-adjustment of the dose and medical regimen based on the severity of pain. Polymedication correlated positively with nonadherence. Nonsteroidal anti-inflammatory drugs were the most frequently prescribed medications. The majority of the participants (59%) believed that higher pain intensity indicates progression of the disease, and half of the participants believed that one can easily become addicted to pain medications. Nonadherence was associated with patient attitudes about addiction to analgesics and ability of analgesics to control pain. CONCLUSION.: High pain intensity and nonadherence found in this study suggest that physicians should monitor older patients with chronic nonmalignant pain more closely and pay more attention to patients' beliefs regarding analgesics to ensure better adherence to pharmacological therapy.

Clinical overview of fibromyalgia

Fibromyalgia (FM) is a complex disorder that affects up to 5% of the general population worldwide, more frequently in women than in men. In addition to chronic widespread pain, patients with FM usually experience other characteristic symptoms, including fatigue, disturbed sleep, stiffness, reduced functioning, dyscognition, and depressed mood. Many patients also have comorbid conditions such as depression, irritable bowel syndrome, temporomandibular disorder, or migraine. Although the etiology of FM remains unclear, evidence suggests that biologic, genetic, and environmental factors are involved. The variability of symptoms and the frequency of comorbidities among patients with FM make this a difficult disorder to diagnose. Diagnosis may be further complicated by the stigmatization of this disorder among treatment providers, the health insurance industry, and the general population. Treating chronic pain disorders such as FM can be time consuming and costly, and other issues such as polypharmacy, treatment adherence, and access to treatment often need to be addressed. The aim of this article is to provide physicians with a general overview of FM, including a brief review of the pathophysiology that explains the biologic and genetic bases of this disorder. Also included is a synopsis of new diagnostic criteria and other useful diagnostic tools and a discussion of various treatment challenges and strategies.

The patient-provider relationship in chronic pain

The relationship between patient and provider has long been the subject of study within the psychotherapy literature, with the available data suggesting a modest, but reliable, association between the strength of this relationship and treatment outcome. Conversely, there has been little work focused on the patient-provider relationship in chronic pain settings despite the complexities and difficulties that are often involved in this area. This review provides a brief, broad overview of the literature on the patient-provider relationship and identifies key aspects that are specifically relevant to chronic pain settings. In addition to reviewing the literature in this area, a series of recommendations for future clinical and academic work are offered.

Determinants of discordance in patients' and physicians' rating of rheumatoid arthritis disease activity

OBJECTIVE

To assess the determinants of patients' (PTGL) and physicians' (MDGL) global assessment of rheumatoid arthritis (RA) activity and factors associated with discordance among them.

METHODS

A total of 7,028 patients in the Quantitative Standard Monitoring of Patients with RA study had PTGL and MDGL assessed at the same clinic visit on a 0-10-cm visual analog scale (VAS). Three patient groups were defined: concordant rating group (PTGL and MDGL within ±2 cm), higher patient rating group (PTGL exceeding MDGL by >2 cm), and lower patient rating group (PTGL less than MDGL by >2 cm). Multivariable regression analysis was used to identify determinants of PTGL and MDGL and their discordance.

RESULTS

The mean ± SD VAS scores for PTGL and MDGL were 4.01 ± 2.70 and 2.91 ± 2.37, respectively. Pain was overwhelmingly the single most important determinant of PTGL, followed by fatigue. In contrast, MDGL was most influenced by swollen joint count (SJC), followed by erythrocyte sedimentation rate (ESR) and tender joint count (TJC). A total of 4,454 (63.4%), 2,106 (30%), and 468 (6.6%) patients were in the concordant, higher, and lower patient rating groups, respectively. Odds of higher patient rating increased with higher pain, fatigue, psychological distress, age, and morning stiffness, and decreased with higher SJC, TJC, and ESR. Lower patient rating odds increased with higher SJC, TJC, and ESR, and decreased with lower fatigue levels.

CONCLUSION

Nearly 36% of patients had discordance in RA activity assessment from their physicians. Sensitivity to the "disease experience" of patients, particularly pain and fatigue, is warranted for effective care of RA.

Quality of life and level of anxiety in youths with inflammatory bowel disease in Ireland

OBJECTIVE

Little is known of the psychological well-being of youths diagnosed as having inflammatory bowel diseases (IBDs). Much of the literature available focuses on adults with IBD and those that focus on youths tend to use generic measures of health-related quality of life (QOL). The primary aim of this research is to obtain a profile of the IBD-related QOL and levels of anxiety of youths of ages 9 to 17 years presenting with IBD to a national hospital. It is also intended to examine the clinical utility of the IMPACT-III questionnaire.

PATIENTS AND METHODS

A questionnaire battery containing the IMPACT-III questionnaire and the Spence Children's Anxiety Scale (SCAS) was posted to all of the patients on the database of the gastrointestinal clinic between the ages of 9 and 17 years (n = 215), resulting in an achieved sample size of 79 (response rate of 36.7%).

RESULTS

It was found that 63% (n = 50) of participants had total IMPACT-III scores below the cutoff of 143, previously established for remission. In addition, 5 participants reported being unhappy with their lives. Thirty-nine percent (n = 31) of participants had elevated anxiety symptoms on ≥ 1 of the SCAS subscales. Anxiety level was found to be a significant predictor of QOL (β = -0.616, P = 0.001). Qualitative feedback highlighted the variability of physical and psychological symptoms participants experience, feelings of anger or embarrassment around the condition, and posed numerous questions, indicating that there is a lack of knowledge among patients around IBD.

CONCLUSIONS

These findings support the utility of screening patients with IBD for psychological difficulties and estimates of QOL. Further research and group interventions are recommended.

Prescription analgesic use among young adults: adherence to physician instructions and diversion

OBJECTIVES

To understand the extent to which medication adherence was related to diversion of prescription analgesics.

DESIGN

Cross-sectional analyses of data from the College Life Study, a prospective study of young adults.

SETTING

Participants were originally sampled as incoming first-time first-year college students from one large public university in the Mid-Atlantic United States.

PARTICIPANTS

One hundred ninety-two young adults aged 21-26 who were prescribed an analgesic to treat acute pain in the past year.

OUTCOME MEASURE

Diversion of prescription analgesics. The study tested two competing hypotheses: 1) individuals who skip doses (under-users) are at greatest risk for diversion because they have leftover medication; and 2) individuals who over-use their prescriptions (over-users) are at greatest risk for diversion, perhaps because of a general propensity to engage in deviant behavior.

RESULTS

Fifty-eight percent followed physician's instructions regarding their prescription analgesic medication; 27% under-used their prescribed medication and 16% over-used their prescribed medication. Twenty-seven percent of the total sample diverted their medication, with over-users being the most likely to divert (63%). Holding constant demographic characteristics and perceived harmfulness of nonmedical use, over-users were almost five times as likely as adherent users to divert analgesic medications (P < 0.05).

CONCLUSIONS

Further research is needed to better understand the relationship between adherence and diversion. If these findings are replicated, physicians who are involved in pain management for acute conditions among young adults should take steps to monitor adherence and reduce diversion of prescription analgesics.

Concerns about medication and medication adherence in patients with chronic pain recruited from general practice

This study examines the concerns and beliefs about medication reported by patients with nonmalignant chronic pain encountered within general practice. Two hundred thirty-nine patients with chronic pain took part in this research. Patients completed the Pain Medication Attitudes Questionnaire, a measure of patient concerns and beliefs relating to addiction, withdrawal, side effects, mistrust in doctors, perceived need of medication, scrutiny from others, and tolerance. The data revealed that patient concerns and beliefs predicted general medication nonadherence. In addition, concerns were related to the direction of nonadherence: overuse of medication was related to increased perceived need for medication and greater concern over side effects; underuse was related to decreased concerns over withdrawal and increased mistrust in the prescribing doctor. Analyses also indicated that patient attitudes and concerns about medication were more predictive of nonadherence than both level of pain and the reported frequency of experienced side effects. This research contributes to the increasing evidence that patient attitudes and beliefs about pain medication are associated with adherence behavior. Training general practitioners to identify and address these concerns may reduce concerns, improve adherence, and facilitate the doctor-patient relationship.

Cognitive Factors in Fibromyalgia: The Role of Self-Concept and Identity Related Conflicts

Fibromyalgia is a syndrome characterized by the presence of diffuse and chronic musculoskeletal pain of unknown etiology. Clinical diagnosis and the merely palliative treatments considerably affect the patient's experience and the chronic course of the disease. Therefore, several authors have emphasized the need to explore issues related to self in these patients. The repertory grid technique (RGT), derived from personal construct theory, is a method designed to assess the patient's construction of self and others. A group of women with fibromyalgia (n = 30) and a control group (n = 30) were assessed using RGT. Women with fibromyalgia also completed the Fibromyalgia Impact Questionnaire and a visualanalogue scale for pain, and painful tender points were explored. Results suggest that these women had a higher present self–ideal self discrepancy and a lower perceived adequacy of others, and it was more likely to find implicative dilemmas among them compared to controls. These dilemmas are a type of cognitive conflict in which the symptom is construed as “enmeshed” with positive characteristics of the self. Finally, implications of these results for the psychological treatment of fibromyalgia are suggested to give a more central role to self-identity issues and to the related cognitive conflicts.

Primary care physical therapy in people with fibromyalgia: opportunities and boundaries within a monodisciplinary setting

Despite the fact that people with fibromyalgia syndrome (FMS) frequently are seen by primary care physical therapists, guidelines for the management of FMS are based primarily on outcomes from multidisciplinary and tertiary care treatment studies. Few data addressing the treatment of patients with FMS in primary care currently are available. The evidence-based guidelines on the management of FMS are based, in part, on evidence from studies examining physical therapy treatment components alone (eg, aerobic exercise, education). Thus, the recommendations can be applied to primary care physical therapy. Primary care physical therapy for patients with FMS should include education, aerobic exercise, and strengthening exercise. For other treatment components such as passive treatments, activity management, and relaxation, less evidence currently is available to advocate their use in primary care physical therapy. Superior results are to be expected when various treatment components are combined.

New and emerging therapeutic agents for the treatment of fibromyalgia: an update

Fibromyalgia (FM) is a chronic widespread pain condition that is estimated to affect 5 million US adults. Several molecular pathophysiologies are thought to contribute to the symptoms of FM, complicating the development of effective clinical management techniques. It is now known that abnormalities in both nociceptive and central pain processing systems are necessary (but perhaps not sufficient) to condition the onset and maintenance of FM, producing associated neuropsychologic symptoms such as pronounced fatigue, sleep abnormalities, cognitive difficulties, stress sensitivity, anxiety, and depression. Current treatment strategies are focused primarily on correcting the pathophysiologic mechanisms underlying these nervous system abnormalities. Clinical studies demonstrate the safety and efficacy of three drugs recently approved for the treatment of FM: pregabalin (an alpha-2-delta ligand), and duloxetine and milnacipran (serotonin/norepinephrine reuptake inhibitors). This review describes these pharmaceuticals in detail and discusses their current roles in FM management.

Engagement in multidisciplinary interventions for pediatric chronic pain: parental expectations, barriers, and child outcomes

OBJECTIVES

To examine the adherence to the recommendations of pain treatment among children and adolescents evaluated for a variety of chronic and recurrent pain conditions.

METHODS

Several measures during initial evaluation and after 3 months were collected to assess satisfaction with initial evaluation, adherence to multidisciplinary recommendations, pain ratings, somatic symptoms, functional limitations, and school attendance.

RESULTS

Of the 120 patients who initially enrolled in the study, 70 parents and 57 children participated in 3-month follow-up interviews and reported significantly fewer doctor visits, decreased somatic symptoms, fewer functional limitations, and decreased pain compared with their initial evaluation. Adherence to multidisciplinary recommendations ranged from 46.7% to 100% with the highest level of overall adherence to physical therapy. Factors associated with adherence varied across type of recommendation. For medical recommendations, higher parent-reported patient satisfaction and expectations that medical tests would be beneficial were associated with engagement in medical treatment, whereas parent reports of negative attitude-type barriers and experience with surgery were associated with less frequent engagement in recommended treatment. With regard to physical therapy recommendations, only earlier experience with exercise was associated with better adherence. For psychologic recommendations, familiarity with hypnosis and biofeedback in addition to positive expectations regarding psychologic treatment and biofeedback were all associated with subsequent engagement in psychologic treatment. Lastly, we identified modest associations between functional improvements and adherence to specific recommendations.

DISCUSSION

Results of this study support the importance of examining adherence to multidisciplinary interventions among children and adolescents with chronic pain.

A randomized controlled trial of a wellness intervention for women with fibromyalgia syndrome

OBJECTIVE

To examine the effects of a wellness intervention, Lifestyle Counts, for women with fibromyalgia syndrome on the level of self-efficacy for health-promoting behaviours, health-promoting activity and perceived quality of life.

DESIGN

A randomized controlled single-blinded trial with treatment and attention-control groups.

SETTING

Community in the southwestern United States.

SUBJECTS

Convenience sample of 187 women (98 treatment, 89 attention control) with fibromyalgia syndrome (mean age = 53.08 years, SD 9.86).

INTERVENTION

The two-phase Lifestyle Counts intervention programme included lifestyle change classes for eight weeks, with goal-setting and telephone follow-up for three months. Participants in the attention-control group were offered an equivalent amount of contact in classes on general disease-related information and health education topics and unstructured follow-up phone calls. Participants were followed for a total of eight months after baseline.

OUTCOME MEASURES

Self-report instruments measuring self-efficacy for health behaviours, health-promotion behaviours and health-related quality of life (SF-36 and the Fibromyalgia Impact Questionnaire) were completed at baseline, two months (after the classes), five months (after telephone follow-up) and at eight months.

RESULTS

Both groups improved significantly (P<0.05) over time on the measures of self-efficacy, health behaviours, fibromyalgia impact and quality of life. There were significant group x time interactions for scores on the Health Promoting Lifestyle II subscales of physical activity and stress management.

CONCLUSIONS

The Lifestyle Counts wellness intervention holds promise for improving health-promoting behaviours and quality of life of women with fibromyalgia syndrome.

Predictors of disability and pain six months after the end of treatment for fibromyalgia

OBJECTIVES

The goal of this study was to identify factors associated with decreased disability and lower pain scores 6 months after a multimodal treatment program for fibromyalgia (FM).

METHODS

Forty-six patients with FM were assessed after having participated in a 3-month outpatient program integrating physiotherapy, occupational therapy, nursing, and cognitive-behavior therapy. A physician examined the patients before treatment and patients who completed a battery of psychosocial questionnaires at baseline, during treatment, at the end of treatment, and 3 and 6 months after the end of treatment. Two separate multivariable linear regression models were built to identify predictors of improvements in disability and pain.

RESULTS

Two predictors for improvement in disability were found: an increase in self-efficacy for pain during treatment and better general adherence during treatment. Similarly, one predictor for improvement in pain intensity was found: an increase in self-efficacy for pain during treatment.

DISCUSSION

Self-efficacy and adherence are 2 modifiable factors that influence disability and pain intensity in FM. These psychosocial factors need to be addressed in FM treatment programs to assist patients in maintaining posttreatment improvements.

Developing a dyadic OPTION scale to measure perceptions of shared decision making

OBJECTIVE

Our aim was to develop a measurement which enables research into the interdependent nature of clinical encounters. The prime objective was to develop an instrument capable of assessing the extent to which patients have been involved in (shared) decision making from two viewpoints-that of the patient and the clinician.

METHODS

To develop an initial 'dyadic OPTION' instrument, the twelve original third-person items were drafted in passive, first person plural forms. Using this version initially, three rounds of cognitive debriefing interviews were held. These were audio-recorded and analysed at the end of each round and the results used to revise the dyadic OPTION scale.

RESULTS

It was possible to modify the observer OPTION instrument into an instrument for completion by both clinicians and patients after a dyadic interaction. Cognitive debriefing revealed five areas of interpretative difficulty. Each item of the observer OPTION scale underwent modification in order to develop a dyadic version of the scale.

CONCLUSIONS

The dyadic OPTION scale is acceptable and comprehensible by both clinicians and public respondents. Cognitive debriefing adapted and refined an existing scale and provided confidence that the core constructs of the scale (perceived involvement in decisions making) were understood.

PRACTICE IMPLICATIONS

Further validation of the dyadic OPTION scale is required prior to its use in research settings.

Preliminary validity of the barriers to treatment adherence questionnaire in fibromyalgia: combining quantitative and focus group data

The goals of this study were to (1) provide preliminary reliability and validity of the Barriers to Treatment Adherence Questionnaire, developed for patients with fibromyalgia, and (2) examine barriers to adherence and general adherence to multimodal treatment during a 3-mo. period. A secondary goal was to explore in a focus discussion group format patients' perceptions of the adherence process and ways of managing the treatment program. 39 fibromyalgia patients were followed while participating in a combined outpatient program of physiotherapy, occupational therapy, nursing, and cognitive behavioral therapy. The Barriers to Treatment Adherence Questionnaire demonstrated good reliability. Construct validity of the Barriers to Treatment Adherence Questionnaire was supported through significant positive correlations with the General Adherence Scale at Months 1 and 3. In addition, a significant change was observed in scores on the Barriers to Treatment Adherence Questionnaire for the physiotherapy component of treatment, with scores decreasing between Months 2 and 3. Addressing barriers to improve adherence may maximize the benefit of treatment programs.

The effect of physician-patient collaboration on patient adherence in non-psychiatric medicine

OBJECTIVE

Factors contributing to treatment adherence are poorly understood but the physician-patient interaction is one factor that is known to affect patient adherence.

METHODS

This meta-analysis systematically reviewed the published literature to determine the magnitude of the relationships between physician-patient collaboration and patient adherence.

RESULTS

A statistically significant weighted mean effect size of M(d)=0.145 from 48 published studies indicated better physician-patient collaboration is associated with better patient adherence. The relationship between collaboration and adherence was sustained for pediatric and adult populations, chronic and acute conditions, and primary physician and specialists.

CONCLUSION

These results emphasize the need for physician-patient collaboration within the medical consultation.

PRACTICE IMPLICATIONS

The inclusion of the patient's perspective during the consultation is essential to obtaining cooperation once the patient has left the physician's office.

Older people's experiences of patient-centered treatment for chronic pain: a qualitative study

INTRODUCTION

Older adults with chronic pain who seek treatment often are in a health care environment that emphasizes patient-directed care, a change from the patriarchal model of care to which many older adults are accustomed.

OBJECTIVE

To explore the experiences of older adults seeking treatment for chronic pain, with respect to patient-directed care and the patient-provider relationship.

DESIGN

In-depth interviews with 15 Caucasian older adults with chronic pain who had been evaluated at a university-based pain clinic. All interviews were audiotaped and the transcripts were analyzed using a grounded theory based approach.

RESULTS

Older adults with chronic pain vary in their willingness to be involved in their treatment decisions. Many frequently participate in decisions about their pain treatment by asking for or refusing specific treatments, demanding quality care, or operating outside of the patient-provider relationship to manage pain on their own. However, others prefer to let their provider make the decisions. In either case, having a mutually respectful patient-provider relationship is important to this population. Specifically, participants described the importance of "being heard" and "being understood" by providers.

CONCLUSIONS

As some providers switch from a patriarchal model of care toward a model of care that emphasizes patient activation and patient-centeredness, the development and cultivation of valued patient-provider relationships may change. While it is important to encourage patient involvement in treatment decisions, high-quality, patient-centered care for older adults with chronic pain should include efforts to strengthen the patient-provider relationship by attending to differences in patients' willingness to engage in patient-directed care and emphasizing shared decision-making.

Medication adherence in patients with chronic non-malignant pain: is there a problem?

Health care providers, treating patients with chronic non-malignant pain, often experience that medication is not as effective as expected. It is important to realize that the effectiveness of a pharmacological treatment can be influenced by the way the medication is taken. Medication adherence is a topic that gains more attention, especially in chronic conditions, because it affects treatment outcome. A systematic review of studies on medication adherence in patients with chronic non-malignant pain was performed to gain insight in the prevalence of the problem, the impact on treatment outcome, influencing variables and interventions. Searching several electronic databases (Medline, CINAHL, Psychinfo and Cochrane), 14 relevant articles were found. The results indicate that medication non-adherence is common in patients with chronic non-malignant pain. Both overuse and underuse of medication occurs. However, due to the scarce literature and important methodological limitations, it is not possible to make firm conclusions concerning the impact on outcome, influencing variables and optimal intervention strategies. This review highlights some important gaps in the adherence literature in a chronic non-malignant pain population and sets the stage for future research.

Illness severity and total visits in family medicine

OBJECTIVE

The purpose of this study was to estimate the independent effect of clinical severity on visit utilization by family medicine patients so that disease management programmes can be targeted accurately and immediately towards patients most likely to benefit from them.

DESIGN

A convenience sample of 698 primary care patients was analysed. All patients had been referred to a medical specialist. Utilization of all types of medical services including laboratory, radiology and ancillary services was used to classify patients as high-utilizers (the top 20%) or not high-utilizers. Patients were stratified into three severity categories based on point scores assigned to specific diseases. The diagnoses included in the Charlson severity index were used to score each patient and the Charlson point scores were used to measure severity. The odds of being a high-utilizer were adjusted for severity category and demographic variables.

RESULTS

Severity was independently related to the odds of being a high-user (adjusted odds ratio = 2.7 for severity = 1 and 5.7 for severity = 2, with the reference category being severity = 0). Age was related to high-use in univariate analyses but not in multivariate analyses.

CONCLUSIONS

Case management programmes in primary care practices should consider using disease severity to identify cases. Severity data can be abstracted by medical secretaries who review narrative problem lists as well as billing codes.

Instruments to assess the perception of physicians in the decision-making process of specific clinical encounters: a systematic review

Background

The measurement of processes and outcomes that reflect the complexity of the decision-making process within specific clinical encounters is an important area of research to pursue. A systematic review was conducted to identify instruments that assess the perception physicians have of the decision-making process within specific clinical encounters.

Methods

For every year available up until April 2007, PubMed, PsycINFO, Current Contents, Dissertation Abstracts and Sociological Abstracts were searched for original studies in English or French. Reference lists from retrieved studies were also consulted. Studies were included if they reported a self-administered instrument evaluating physicians' perceptions of the decision-making process within specific clinical encounters, contained sufficient description to permit critical appraisal and presented quantitative results based on administering the instrument. Two individuals independently assessed the eligibility of the instruments and abstracted information on their conceptual underpinnings, main evaluation domain, development, format, reliability, validity and responsiveness. They also assessed the quality of the studies that reported on the development of the instruments with a modified version of STARD.

Results

Out of 3431 records identified and screened for evaluation, 26 potentially relevant instruments were assessed; 11 met the inclusion criteria. Five instruments were published before 1995. Among those published after 1995, five offered a corresponding patient version. Overall, the main evaluation domains were: satisfaction with the clinical encounter (n = 2), mutual understanding between health professional and patient (n = 2), mental workload (n = 1), frustration with the clinical encounter (n = 1), nurse-physician collaboration (n = 1), perceptions of communication competence (n = 2), degree of comfort with a decision (n = 1) and information on medication (n = 1). For most instruments (n = 10), some reliability and validity criteria were reported in French or English. Overall, the mean number of items on the modified version of STARD was 12.4 (range: 2 to 18).

Conclusion

This systematic review provides a critical appraisal and repository of instruments that assess the perception physicians have of the decision-making process within specific clinical encounters. More research is needed to pursue the validation of the existing instruments and the development of patient versions. This will help researchers capture the complexity of the decision-making process within specific clinical encounters.
